Overclocking Phenom II X4

post #1 of 6
Thread Starter 
Hi, I want to overclock my Phenom II x4. My mobo is MA785GM-US2H, so I was wondering if someone can tell how to do so in the BIOS? Thanks

One more thing is there more than one way to overclock in BIOS (i:e increase multiplier & voltage or increase FSB, HT....etc) Thanks

Hi.

What specific Phenom II X4 model do you have? Do you have some experience with overclocking before? What cooler do you have?

Take a look of this two guides.

1- http://www.overclock.net/amd-general...rclocking.html
2- http://www.overclock.net/amd-general...ing-guide.html

As you say, that CPU have two ways for overclock. Multiplier and FSB, I recommend you use the multiplier. You also will need a better cooler.

1- Multiplier: You only change the CPU frequency, keep in mind that the formula is this: reference clock (200MHz) x CPU multiplier (x17)= = CPU frequency (3400MHz). You will need add voltage to the CPU in some points for get it stable, but don't go above 1.5V and 55ºC or you can have problems.

2- FSB: With this you also can change the CPU frequency, but the FSB is linked with the HT, NB and DRAM frequency, so, you get more troubles for get all the rig stable that only with multiplier.

Only the BE CPUs like your can be overclocked using multiplier

Not a good motherboard for 125W CPU overclocking.
The MA785GM-US2H uses an older 4+1 VRM design that unlike most others which are rated 140W, is only rated 125W. This older 4+1 VRM design is known for problems and failures. It is not ready to accomodate an overclock of 125W processor.
(See the links in my sig for more info).
I have heard from people who went ahead and overclocked anyway on this board or another board with similar VRM design. After a month to a couple of months, both experienced the problem of loud noise coming from the VRM areas, due to over-current.

A new motherboard may be warranted for proper overclocking experience.

Thanks for your help so far Saint19, where exactly can I locate the multiplier in my mobo in order to increase it? I know how to increase the CPU Voltage.
